Archives List – Make Month link to appropriate page

OK. I have a list of archives here
https://theworldwidenews.info/sitemap/

The code I have is

<?php

	// Declare some helper vars
	$previous_year = $year = 0;
	$previous_month = $month = 0;
	$ul_open = false;

	// Get the posts
	$myposts = get_posts('numberposts=-1&orderby=post_date&order=DESC');

	?>

<?php foreach($myposts as $post) : ?>	

	<?php

	// Setup the post variables
	setup_postdata($post);

	$year = mysql2date('Y', $post->post_date);
	$month = mysql2date('n', $post->post_date);
	$day = mysql2date('j', $post->post_date);

	?>

	<?php if($year != $previous_year || $month != $previous_month) : ?>

		<?php if($ul_open == true) : ?>
		</ul>

		<?php endif; ?>

		<br />
		<h3><?php the_time('F Y'); ?></h3>

		<ul id="archive-list" class="clearfloat">

		<?php $ul_open = true; ?>

	<?php endif; ?>

	<?php $previous_year = $year; $previous_month = $month; ?>

	<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> <span class="commentcount">(<?php comments_number('0', '1', '%'); ?>)</span></li>

<?php endforeach; ?>
			</ul>

Call me dumb, but I cant figure out how to make the month link to the appropriate page in the archives. Can anyone help? My eternal devotion is assured.
